Let's divide 66123201 by 576
We're looking to find how many times 576 goes into 66123201.

Step 1:
6 divided by 576 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 576

Advancing to step 2:
When dividing 66 by 576, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 576

Advancing to step 3:
When dividing 661 by 576, we get 1 with a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 576 from 661 and we're left with 85.
Grab the next digit (2) from the dividend, add it to 85, then carry on: 852 / 576

Step 4:
If we divide 852 by 576, we get 1 and a remainder of 276.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 576 from 852 and we're left with 276.
Include the next digit (3) from the dividend after 276, then repeat: 2763 / 576

Step 5:
576 can be fit into 2763 4 times, resulting in a remainder of 459.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtract 2304 from 2763 to get 459.
Grab the next digit (2) from the dividend, add it to 459, then carry on: 4592 / 576

Moving on to step 6:
When dividing 4592 by 576, we get 7 with a remainder of 560.
Record the quotient 7 as the next digit in the result. 
Result so far: 1147.0
The remainder is 560 after subtracting 4032 from 4592.
Fetch the next digit (0) from the dividend, attach it to 560 and continue: 5600 / 576

Advancing to step 7:
5600 divided by 576 is 9 with a remainder of 416.
Put 9 as the next digit of the answer. 
Result so far: 11479.0
If we subtract 5184 from 5600, we get 416.
Take the next digit (1) from the dividend and append it to 416, then repeat: 4161 / 576

Step 8:
The number 576 fits into 4161 7 times, leaving a remainder of 129.
The next digit of our result is 7. 
Result so far: 114797.0
The remainder is 129 after subtracting 4032 from 4161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 9:
When dividing 1290 by 576, we get 2 with a remainder of 138.
Write down 2 as next digit of the result. 
Result so far: 114797.2
Deduct 1152 from 1290 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 10:
The number 576 fits into 1380 2 times, leaving a remainder of 228.
Record the quotient 2 as the next digit in the result. 
Result so far: 114797.22
Subtracting 1152 from 1380 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The quotient of the division is 114797.22, and the remainder is 0.228.
